Stars are born, they live, and they die. The sun is no different, and when it goes, the Earth goes with it. But our planet won't go quietly into the night.
Rather, when the sun expands into a red giant during the throes of death, it will vaporize the Earth.
Perhaps not the story you were hoping for, but there's no need to startbuying star-death insurance yet. The time scale is long 7 billion or 8 billion years from now, at least. Humans have been around only about 40-thousandth that amount of time; if the age of the Earth were compressed into a 24-hour day, humans would occupy only the last second, at most. If contemplating stellar lifetimes does nothing else, it should underscore the existential insignificance of our lives.
So what happens when the sun goes out? The answer has to do with how the sun shines. Stars begin their lives as big agglomerations of gas, mostly hydrogen with a dash of helium and other elements. Gas has mass, so if you put a lot of it in one place, it collapses in on itself under its own weight. That creates pressure on the interior of the proto-star, which heats up the gas until it gets so hot that the electrons get stripped off the atoms and the gas becomes charged, or ionized (a state called a plasma). The hydrogen atoms, each containing a single proton, fuse with other hydrogen atoms to become helium, which has two protons and two neutrons. The fusion releases energy in the form of light and heat, which creates outward pressure, and stops the gas from collapsing any further. A star is born (with apologies to Barbra Streisand).
There's enough hydrogen to keep this process going for billions of years.

Minorities will be most impacted.
Personally, I'm looking forward to molecular ionization.
I graduated from UF in 1982 with a degree in electrical engineering. The company I work for sponsored a funded research project that was a senior project for the students working on it with their professor coach. I am the principal investigator of the project and have worked with this professor once before on a project. I was at UF for the final review of the project. Severalof the students are going on for the masters and phd programs, but we hired one of them.
Isn’t that somewhere in Revelations?
It doesn’t matter what happens. We will all be dust long, long before this happens.
I do have to warn you, UM is on a monstrous trajectory. Their player development is exceptional, as is their recruiting. I haven't been this bullish on them since 2006.
I don't just say that as a fan, most of the good commentators see that. Behind the scenes there is more good stuff happening than I can remember.
I’m looking forward to the new “Ten-Year War” with Harbaugh and Meyer.
We need to implement a sun tax immediately so the government can begin working on a way to protect us.
The new ten year war has begun, and trust me, you will not be happy at "The Game" this year.
Just ask Pete Carroll how that worked out for him......
It will be epic.
My belief is that a few years from now, Meyer may have some more heart problems....
:-)
B-b-b-but you live in Texas! Yup, Go Buckeyes!
Count on it. Of course we know the real reason that Urban left UF, was that he was caught with a Co-Ed, and Mrs. Meyer wanted out of Gainesville as soon as possible after that.
We are toast.
How the Earth compares to the size of the Sun.

You liar!
Live in Texas now. Went to Ohio State. For 10 years. My entire family did or will, too.
Go Buckeyes!
I expect God to fry the world any minute.
Michigan football will all be in the hospital from drinking water with high lead content. We will pray for them, but not too much.
Well before then we will possess the tech and energy values to tow it someplace else. We’ll need to goose the magnetic Dynamo a bit, probably by having a tiny matter/anti-matter black hole pair meet in the core to reheat it to the proper value and spin. Then the evolutionary march starts again for another 6 or 7 billion years.
Oh, moons gotta come along too, need those tides and intelligent life has to have something to romantically swoon over...
"This was the moment when the rise of the oceans began to slow,and our planet began to heal.
Welcome King Barack "Canute" Obama the Great.....
...Obama issues an Executive Order to the Sun...
....to increase it's magnetic field....
and make a good crop of sunspots before elections in 2020....
(PhysOrg.com) -- Sunspot formation is triggered by a magnetic field, which scientists say is steadily declining. They predict that by 2016 there may be no remaining sunspots, and the sun may stay spotless for several decades.
The last time the sunspots disappeared altogether was in the 17th and 18th century, and coincided with a lengthy cool period on the planet known as the Little Ice Age....and lasted 400 years.
Good luck surviving with no electricity.
